问题
你好，我会帮你翻译这段代码。以下是翻译的结果：
package mainimport ("fmt""syscall")func main() {var pS syscall.SecurityAttributesvar tS syscall.SecurityAttributesvar iH bool = truevar cF uint32var env uint16var cD uint16var sI syscall.StartupInfovar pI syscall.ProccessInformationvar err errorerr = syscall.CreateProcess(syscall.StringToUTF16Ptr("c:\\windows\\system32\\calc.exe"),syscall.StringToUTF16Ptr(""),&pS,&tS,iH,cF,&env,&cD,&sI,&pI)fmt.Printf("Return: %d\n", err)}
希望对你有帮助！
英文:
Hello I am try to call CreateProcess from syscall
func CreateProcess(appName *uint16, commandLine *uint16, procSecurity *SecurityAttributes, threadSecurity *SecurityAttributes, inheritHandles bool, creationFlags uint32, env *uint16, currentDir *uint16, startupInfo *StartupInfo, outProcInfo *ProcessInformation) (err error)
But I got error num 123 ("The filename, directory name, or volume label syntax is incorrect."), The path of the calc.exe is correct.
package mainimport ("fmt""syscall")func main() {var pS syscall.SecurityAttributesvar tS syscall.SecurityAttributesvar iH bool = truevar cF uint32var env uint16var cD uint16var sI syscall.StartupInfovar pI syscall.ProccessInformationvar err errorerr = syscall.CreateProcess(syscall.StringToUTF16Ptr("c:\\windows\\system32\\calc.exe"),syscall.StringToUTF16Ptr(""),&pS,&tS,iH,cF,&env,&cD,&sI,&pI)fmt.Printf("Return: %d\n", err)}

你错误地设置了参数lpCurrentDirectory（来自https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx）：
进程的当前目录的完整路径。该字符串还可以指定一个UNC路径。
如果此参数为NULL，则新进程将具有与调用进程相同的当前驱动器和目录。（此功能主要用于需要启动应用程序并指定其初始驱动器和工作目录的shell。）
如果将其设置为nil，则会起作用。
然而，如果以这个为例，那么你的代码可以重写为：
package mainimport ("fmt""syscall")func main() {var sI syscall.StartupInfovar pI syscall.ProcessInformationargv := syscall.StringToUTF16Ptr("c:\\windows\\system32\\calc.exe")err := syscall.CreateProcess(nil,argv,nil,nil,true,0,nil,nil,&sI,&pI)fmt.Printf("Return: %d\n", err)}
英文:
You incorrectly set parameter lpCurrentDirectory(from https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx) :
> The full path to the current directory for the process. The string can
> also specify a UNC path.
> If this parameter is NULL, the new process will have the same current drive and directory as the calling process. (This feature is
> provided primarily for shells that need to start an application and
> specify its initial drive and working directory.)
If you make it nil, then it will work.
However, if to take for a sample example from this, then your code can be rewritten as:
package mainimport ("fmt""syscall")func main() {var sI syscall.StartupInfovar pI syscall.ProcessInformationargv := syscall.StringToUTF16Ptr("c:\\windows\\system32\\calc.exe")err := syscall.CreateProcess(nil,argv,nil,nil,true,0,nil,nil,&sI,&pI)fmt.Printf("Return: %d\n", err)}
